By exploring evidence, identifying biases, and considering both supportive and contradictory data, you can foster smarter, more resilient decision-making.

• Internal Environment: Beliefs about team capabilities, processes, or resource availability.
• Other: Any assumptions that don’t fit neatly into the above categories.‍

‍
Supporting Data

Challenging Data
Include any evidence or observations that contradict or undermine the assumption. This is critical for fostering balanced thinking and mitigating risks.
